A comparison of reservoir gas energy and composition with respect to initial oil production in the San Andres Formation of Shafter Lake Field, Andrews County, Texas
(2018-05-14)The oil-rich, Permian-age San Andres Formation in the Permian Basin of West Texas produces Wolfcampian-age oil from the dolomitic host rock in prolific amounts. The present study focuses on the Shafter Lake field and ... -
Geomechanical Analysis of Rock Brittleness with Comparisons to the Mineralogical Brittleness Index
(2016-05)A significant area of research within the Oil and Gas industry centers around the understanding of rock brittleness and fracture mechanics related to inducing and extending hydraulic fractures. This study defines rock ... -
PETROPHYSICAL PROPERTIES OF THE WOODFORD FORMATION IN THE ARDMORE BASIN IN OKLAHOMA, U.S.A
(2017-12-04)A prolific source rock in Oklahoma, the Woodford Shale has sourced petroleum reservoirs for millions of years and produced oil and gas since 1939. Not until the shale boom of the early 2000’s was the full potential of the ... -
CHARACTERIZATION OF NANOPETROPHYSICAL PROPERTIES OF THE MANCOS “B”/ PRAIRIE CANYON MEMBER OF THE MANCOS SHALE, RIO BLANCO, COLORADO
(2017-12-04)Over the past decade hydrocarbon production from unconventional reservoirs has grown to become a significant source of North American domestic energy and will likely continue so for decades to come. However, production ... -
Nano-scale Petrophysical Studies of The Gothic Shale Interval in the Paradox Basin, Colorado, U.S.A.
(2017-12-01)Hydrocarbon production from shale has become a main energy source for the United States. Consequently, an increased knowledge of the petrophysical properties of shale such as porosity, permeability, tortuosity, and ... -
Nanopetrophysics Characterization of the Mancos Shale Formation in the San Juan Basin of northwestern New Mexico, U.S.A.
(2017-12-01)The Mancos Shale of the San Juan Basin is no stranger to the drilling of oil and gas, but traditional exploration within the region has predominantly been limited to the use of conventional vertical wells. Due to the recent ... -
Mapping Structural Deformation Associated with the Formation of the Blue Ridge Salt Dome
(2017-12-11)Geologic mapping and subsurface imaging around salt has remained difficult. Seismic imaging is difficult near salt due to the large velocity contrasts between salt and the surrounding rocks, the steeply dipping salt and ... -
Petrophysical Characterization of the Jo Mill Submarine Fan Complex, Spraberry Trend, Midland Basin, Texas
(2017-12-01)Understanding and quantifying reservoir quality require a new suite of knowledge when approaching the nanometer sized pore-networks of unconventional reservoirs. These low porosity and permeability reservoirs have been ... -
MAGNESIUM ISOTOPE INVESTIGATION OF STROMATOLITIC KNOBS IN STORR’S LAKE, SAN SALVADOR, BAHAMAS: IMPLICATIONS FOR ORGANOMINERALIZATION AND LAMINAE FORMATION
(2017-08-21)Storr’s Lake, a hypersaline lake located on San Salvador Island, Bahamas, contains modern, fine-grained stromatolites. This study focused on two morphological types of stromatolitic mounds in Storr’s Lake (pinnacle mound ... -
IMPROVING REGIONAL HYDROLOGY FORECASTING FOR THE NORTH CENTRAL TEXAS REGION UTILIZING CONDITIONAL ENSEMBLE STREAMFLOW AND HYDROMETEOROLOGICAL CONDITION PREDICTIONS WITH ARTIFICIAL NEURAL NETWORK MODELING
(2017-05-10)The predictive skill of hydrologic variables such as streamflow and soil moisture, in North Central Texas, has improved substantially in the recent decades. However, substantial model-data biases are still present during ... -
A MODERN RESERVOIR ANALOG FOR A POORLY DRAINED “HIGH ACCOMMODATION” FLUVIAL SYSTEM: SEDIMENTARY PROCESSES, ARCHITECTURE, AND RESERVOIR CONNECTIVITY OF THE GRIJALVA SYSTEM, TABASCO STATE, MEXICO
(2016-09-12)High-accommodation fluvial systems are subject to much modeling and substantial rock drilling and imagination, but limited modern field observation. The Grijalva River system of Tabasco State, Mexico offers the opportunity ... -
GEOCHEMICAL AND PETROPHYSICAL CHARACTERISTICS OF THE HORN RIVER FORMATION: BRITISH COLUMBIA, CA
(2017-05-23)The Devonian Horn River basin of northeastern British Columbia is the largest producing shale gas field in Canada. It has an estimated 500-600 TCF of light hydrocarbons in place stacked in multiple formations in an ... -
NANO-PETROPHYSICS OF THE HYBRID SHALE-OIL BONE SPRING FORMATION, LEA COUNTY, NEW MEXICO
(2017-05-23)Despite the increased hydrocarbon production in hydraulically stimulated unconventional reservoirs, how fluid flows through the rock matrix in these reservoirs is still not well understood. It has been shown that much of ... -
Tectonic processes and continental hydroclimate during the Laramide deformation in the central Rocky Mountains
(2017-05-12)The central Rocky Mountains in western U.S.A. is a geologic province formed by the low-angle subduction of the Farallon oceanic plate under the North American continental plate during the latest Cretaceous–early Eocene ... -
